How I know things

I am on a fixed income. I have never studied political science. I grew up in an apolitical family. I’m a white ethnic. I am outraged about many things. Now, I am highly educated and very leftie, and yet despite that the griping attitude of the left, in which I myself used to engage, makes me tired, unhappy, and wanting to stay home. That’s how I know.

Rubber-glue defenses only make me angrier and want to vote Republican out of spite. I won’t do that, but I can feel the urge.
